Meet the Baer Heli Coil Tap — a precision tool designed for impeccable thread repairs and reinforcements with Heli-Coil wire thread inserts. Engineered for durability and consistent performance, this Bottoming Tap (STI) delivers clean, full-depth UNC threads every time, specifically sized for 1-3/8 x 6 applications.

Why this Heli Coil Tap stands out

• Bottoming tap design ensures complete thread engagement to the full depth of the hole, which is essential when installing Heli-Coil inserts and when you need reliable, fatigue-resistant threads.
• Tailored for Heli-Coil wire thread inserts, providing precise alignment that minimizes insert binding and maximizes load-bearing capacity.
• UNC compatibility (1-3/8 x 6) covers a broad range of common repair and reinforcement scenarios in automotive, machinery, and equipment maintenance.
• Durable construction built to withstand repeated tapping in tough materials, helping you reduce downtime and extend tool life.
• Versatile for repairs, reinforcements, and new-thread applications where threaded holes must withstand vibration, pull-out, and heavy use.

Practical usage and best practices

1. Prepare the hole to the correct insert size and verify depth to ensure the Heli-Coil insert seats properly.
2. Lubricate and steady your taps, turning slowly clockwise to cut accurate threads without tearing.
3. After tapping, clean away chips, install the corresponding Heli-Coil insert per manufacturer instructions, and test with a fastener to confirm fit and torque behavior.
